Some of our users like @benaadams runs tons of benchmarks, which takes a lot of time (example)

I have a lot of ideas for speed-up.

It includes:

1. Build everything in parallel first and then run each benchmark sequentially to keep the correctness
2. Make sure that only the diagnosers that really need an extra run perform an extra run. For example: the disassembly diagnoser could just attach at the end, the memory diagnoser could get the allocated memory without any overhead for .NET Core in silent mode.
3. Profile everything, make sure we are as fast as possible

I am busy now, but I have no conferences for November/December scheduled so I will finally have some time for bigger changes
